Users can view a selection of animations of ocean surface temperature and dynamic height derived from data from the TAO/TRITON buoy array moored in the Pacific Ocean. The animations show temperature and surface topography variations consistent with the development of El Nino and La Nina events.

This movie shows Venus and Earth as they rotate. The images are superimposed on each other so that differences in rotation speed and tilt of axes can be seen. Links to documents describing the physical properties and characteristics of the two planets are provided.

This animation shows a sequence of daily images of the southern hemisphere in which daily and seasonal fluctuations in the ozone hole over Antarctica can bee seen. The images were captured by the Total Ozone Mapping Spectrometer (TOMS), an instrument carried aboard the Earth Probe spacecraft.

This educational brief provides an overview of the layers of the atmosphere, the effects of the solar wind upon them, and how these effects are mitigated by Earth's magnetic field. It also describes OMNIWeb, an internet-based data retrieval interface for obtaining datasets on solar energetic particles.

This document discusses the history of mass extinctions throughout geologic time, their role in the evolutionary process, and a mathematical model that demonstrates how the evolutionary process might interact with environmental stresses to produce a distribution of extinctions similar to that seen in the fossil record.
